LinuxPlanet :: Making Your Terminal into a Desktop
Written by bibe   
Friday, 17 March 2006
There are several possible reasons why you might choose to use the command line interface (CLI) as your desktop environment. For one thing, it uses less electricity, so you could maximize battery life on your laptop computer. Secondly, it forces you to think about your operating system and directory structure in a totally different way than a GUI does; this could greatly enhance your understanding of GNU/Linux and cause you to be more creative in your technological problem solving. And thirdly, everyone will think you're a supreme computer genius for ditching X11 for the CLI. People passing by your desk will think you're some kind of computer god. Who doesn't want that?

developerWorks :: Access the Linux kernel using the /proc filesystem
Written by bibe   
Wednesday, 15 March 2006
The /proc filesystem is a virtual filesystem that permits a novel approach for communication between the Linux® kernel and user space. In the /proc filesystem, virtual files can be read from or written to as a means of communicating with entities in the kernel, but unlike regular files, the content of these virtual files is dynamically created. This article introduces you to the /proc virtual filesystem and demonstrates its use. Read more on developerWorks
 
The R Zone :: Tracking, auditing and managing your server configuration with Subversion in 10 minute
Written by bibe   
Wednesday, 15 March 2006
Most servers are configured once, then left to run for as long as they can (which, in practical terms, means ‘until hardware or software fails’). More often than not, the cause for server failure is rooted in configuration mistakes. That’s why it’s wise to keep a log of all configuration changes, and take detailed notes every time a setting is changed. But, as the collection of servers you need to manage grows, bookkeeping tasks turn into a humongous monster. No more. Enter Subversion. Read more on The R Zone
 
Ayman Hourieh's Blog :: Tips to Secure Linux Workstation
Written by bibe   
Tuesday, 14 March 2006
While waiting for ADSL to be enabled in my area, which (I've been told) will happen soon, I did some tinkering with my Gentoo Linux workstation to make it more protected against remote attacks, and I thought of compiling a list of security measures against the dangers of full-time Internet connection. Obviously the list is not complete, but it has tips that can surely help. Read more on Ayman Hourieh's Blog

Tuesday, 14 March 2006
Linux system administrators should learn traditional DNS. Front-ends and quick templates to setup domain records have a place in managing sites. When confronted with DNS configurations already in existence, nothing can substitute for knowing and using the fundamentals. Read more on HowtoForge

Monday, 13 March 2006
Existen muchas versiones de Linux en LiveCD, unas basadas en diferentes distribuciones, otras en las mismas, otras basadas en otro LiveCD así que si eres como yo, posiblemente tengas una colección de CD's y disquetes porque nunca se sabe que herramienta puede resultarte efectiva en un momento determinado. Así que me he creado un CD/DVD donde poder disponer de varios LiveCD y programas en disquetes que tengo desperdigados por el cajón. Esto puede ser tan útil como inútil según para quien, pero el caso es que si tu quieres crearte ese CD/DVD aquí tienes el método que yo he usado. Lee màs en NaUtopia.net
 
The R Zone :: 5 minutes to finding issues in production PHP Web applications
Written by bibe   
Monday, 13 March 2006
Detecting and correcting problems with applications at early stages is an important role of the server manager. Unfortunately, not all errors are detected at the testing stages. Even more unfortunate is the fact that most errors go undetected because they are usually triggered when a certain set of criteria is met. Since all you have is 5 minutes (which is one of the tenets of this Server management series, and quite possibly the only simple truth in your case), in this installment, we’ll unlock the secret of server log foraging.

Jonathan Schwartz's Weblog :: Why Free Standards Matter
Written by bibe   
Saturday, 11 March 2006
Imagine you live on a sleepy street in a coastal town, say Rio de Janeiro. And a hurricane or tsunami hits your shores. And the government agency responsible for telling you how and where to get relief, for provisioning aid and emergency services, sends out a curious message: if you can't afford a copy of Microsoft Windows, we're sorry, we can't help you. That's exactly what happened in New Orleans a few months back. Read more on Jonathan Schwartz's Weblog
